duolingo talk to me more offten
From some articles and papers I read in the past I know that important factor in learning language is hearing it and repeating it as much as possible (the best is to repeat whole sentences, not just word).
Dear duolingo, my idea for a new, yet very important feature is this: every time we do task correctly (regardless of whether it is typing, speaking, gaps filling), give us proper pronunciation. Always. I've type sentience correctly? Tell me two pronounce it. I've filled the gap correctly? Tell me two pronounce the whole sentence. I've just pronounced it correctly? Cool, but do it one more time for me.
This ways I keep on "hearing" the language. The sentences are staying in my head.
